Wireless Sensor Networks (WSNs) are event-based systems that rely on the collective effort of several micro-sensor nodes. Reliable event detection at the sink is based on collective information provided by source nodes. When data needs to be gathered from a selected set of nodes and transmit to sink in the network. However the sensor nodes often face the critical challenge among all is the cons...

Yamada, Tomoaki—A politically feasible social security reform with a two-tier structure This paper investigates the welfare implications and political feasibility of social security reforms with a two-tier structure in Japan. We evaluate social security reforms from two points of view: (i) the ex-ante expected value of future generations, and (ii) whether current generations prefer reform to th...

The purpose of this paper is to present the design of a secure and more advanced authentication scheme for executing secure financial transactions over Internet. There has been continuous change in technology day by day, so security mechanisms like authentication schemes are also required to be updated. The security measures have very crucial role in banking and financial sector. For any intern...

We have used five cats to investigate the effects of two distinct visual cortex lesions on the segregation of two different texture stimuli. The ablation of areas 17 and 18 (tier I) severely impaired the segregation between textures made of line elements differing in orientation, but spared the segregation between annulus and dot textures. In contrast, the ablation of those areas receiving dire...

(N2) lymph node stations. The applicability of SNLB in gastric cancer has been studied in recent years in an effort to accurately predict metastasis to (non)regional lymph nodes. The ultimate goal is to identify patients who truly need a lymphadenectomy and to identify patients in whom lymphadenectomy can be omitted. Obviously, patients with suspicious or proven lymph node metastases are not el...

In the owl monkey, microelectrode mapping of Brodmann's area 19 indicates that this region contains part or all of at least 5 separate representations of the visual field, each of which adjoins the anterior border of V II and collectively are termed the third tier of cortical visual areas (V I is the first tier; V II is the second tier). Described in detail in this report is one of the third ti...

Leveraging unmanned aerial vehicles (UAVs) as relays, the space-air-ground integrated Internet of Things (SAG-IoT) networks can provide wireless access services to connected devices with high data rate, flexibility, and wide coverage. However, besides bringing lots benefits, SAG-IoT systems also face many challenges due mobility, unreliable satellite links, limited resources. Especially, when m...
